A member of Congress has asked Intel and AMD to explain the danger consumers face from the chip vulnerabilities

A member of Congress asked Intel, AMD and Arm Holdings about the recently discovered security vulnerabilities affecting their chips.

The questions to the companies came in a letter from California Representative Jerry McNerney, a Democrat who is a member of the House Energy and Commerce Committee.

A Democratic U.S. lawmaker asked Intel and two other microchip makers on Tuesday to provide a briefing on the recently detected Spectre and Meltdown security flaws that could allow hackers to steal information from most computers and devices.

"I am looking to better understand the nature of these critical vulnerabilities, the danger they pose to consumers, and what steps your companies plan to take to protect consumers," California Representative Jerry McNerney wrote to the chief executives of Intel, Softbank-owned Arm Holdings and Advanced Micro Devices.

None of the companies immediately responded to requests for comment.

The request is one of the first responses from the U.S. Congress to the disclosure earlier this month by security researchers of the two major flaws, which may allow hackers to steal passwords or encryption keys on most types of computers, phones and cloud-based servers.

McNerney, a member of the House Energy and Commerce Committee, asked the companies to explain the scope of Spectre and Meltdown, their timeframe for understanding the vulnerabilities, how consumers are affected and whether the flaws have been exploited, among other questions.
